Experimentelle Wirtschaftsforschung kann Verbraucherpolitik unterstützen

Für die einen gilt: "Nur Warnhinweise auf Lebensmitteln können vor der Volksseuche Übergewicht noch retten." Für die anderen hingegen ist klar: "Eine rote Ampel auf kalorienreichen Lebensmitteln bedeutet eine unerträgliche Entmündigung der Bürger." Die aktuelle Kontroverse um die von der EU vorangetriebene Nährwertkennzeichnung von Lebensmitteln zeigt: Verbraucherpolitische Debatten werden häufig mit ...

Overcoming Data Limitations in Nonparametric Benchmarking: Applying PCA-DEA to Natural Gas Transmission

We empirically demonstrate a practical approach of efficiency evaluation with limited data availability in some regulated industries. We apply PCA-DEA for radial efficiency measurement to U.S. natural gas transmission companies in 2007. PCA-DEA reduces dimensions of the optimization problem while maintaining most of the variation in the original data. Our results suggest that the methodology reduces ...

Merger Efficiency and Welfare Implications of Buyer Power

This paper analyzes the welfare implications of buyer mergers, which are mergers between downstream firms from different markets. We focus on the interaction between the merger's effects on downstream efficiency and on buyer power in a setup where one manufacturer with a non-linear cost function sells to two locally competitive retail markets. We show that size discounts for the merged entity has no ...

Removing Cross-Border Capacity Bottlenecks in the European Natural Gas Market: A Proposed Merchant-Regulatory Mechanism

We propose a merchant-regulatory framework to promote investment in the European natural gas network infrastructure based on a price cap over two-part tariffs. As suggested by Vogelsang (2001) and Hogan et al. (2010), a profit maximizing network operator facing this regulatory constraint will intertemporally rebalance the variable and fixed part of its two-part tariff so as to expand the congested ...

Subsidies for Learning in Renewable Energy Technologies under Market Power and Emission Trading

Under perfect competition on the output market, first best technology subsidies in the presence of learning by doing are justified by knowledge spill overs that are not accounted for by individual companies. First best output subsidies are thus depending directly on the learning effects and are, if applicable, positive. Considering electricity markets, a setting of imperfect competition is more appropriate. ...

Entry Regulation and Entrepreneurship: Empirical Evidence from a German Natural Experiment

The amendment to the German Trade and Crafts Code in 2004 offers a natural experiment to asses the causal effects of this reform on the probabilities of being self-employed and transition into and out of self-employment, using cross-sections (2002-2006) of German microcensus data. This study applies the difference-in-differences technique in logit models for four occupational groups. Easing the educational ...
